Priming Catalyst System:
PRIMING CATALYST TO GUN (POUR & SPRAY)
1. Do not use quick pin to install upper catalyst pump bearing block to slave arm at this time.
2. Check that all catalyst hoses and fittings are tight. Remove the Mix Chamber from the front of the
gun (pour and spray).
3. Catalyst jug should be filled at least 3/4 full with appropriate catalyst. Make sure to close the catalyst
recirculation valve on the catalyst manifold.
4a. Pour: To prime catalyst to the Putty Pour Gun, pull manual gun handle (58148-1) all the way back.
The gun handle should engage button on 3-way air valve (09169).
4b. Spray: To prime catalyst to the Putty Spray gun, pull the trigger all the way back and engage the
trigger lock. The mix chamber should not be attached at this time.
5. To prime catalyst system, use priming knob (50100-1) at the top of the catalyst pump. Slowly hand
pump priming knob using long up and down strokes until a steady flow of catalyst is being dispensed
out the gun. Lean the top of the catalyst pump up against the connecting rod
.
NOTE: When hand priming catalyst pump, resistance should increase uniformly between the up-
stroke and the down stroke when building up pressure.
6. Secure leaks, if any
7. Close dispensing head / gun
8. Position outlet of head / gun over a flush container
9. Flush & Air purge as necessary, a sudden purge of material from dispensing head is likely and could
splash, so be cautious
